GILBERT W. WARREN, OF ILION, NEW YORK, ASSIGNOR TO DAISY MANUFACTURING COMPANY, OF PLYMOUTH,

PORATION.

MICHIGAN, A COR- AIR-GUN- Specification of Letters Patent.

Patented Sept. 4, 1 906.

J10 (LZZ whom it may concern:

Be it known that I, GILBERT W. WARREN, a citizen of the United States, residing at Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Air-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

, My invention relates to an improvement in what is commonly known as an air-gun, and it consists in the mechanism hereinafter pointed out and claimed.

The purpose of my invention is to provide a stop within the false barrel and which in this instance consists in a tubular piece of metal slotted or opened in the direction of its length, which is inserted within the false barrel and held stationary by an well-known means, and also to provide an opening through the breech-plug from the magazine into the rear of the true barrel, so that as each shot is fired the remaining shot in the magazine are kept in position to be fed into the true barrel after any particular shot may have been discharged from the gun.

In the drawings, Figure 1 is a vertical longitudinal section of my air-gun, portions of the working parts being shown in full lines and portions in sectional lines, broken lines indicating parts removed. Fig. 2 is a vertical central section of the plug and adjacent parts of my air-gun, broken lines indicating parts removed. Fig. 3 represents a perspective View of the breech-plug, broken lines in dicatingparts removed. Fig. 4 is a perspective View of a tubular stop, slotted in the direction of its length. Fig. 5 is a perspective view of the piston-guide and spring-abutment, and Fig. 6 is a perspective view of the trigger.

Having described my invention with reference to the figures illustrated in the drawings, I will now proceed to describe the same more in detail, in which description similar numerals of reference refer to corresponding parts in the several views.

In constructing my air-gun I provide a true barrel 1, which is su ported at its base or rear at 2 in the magazine breech-plug 3. The rear of the barrel may be mounted. in the magazine breech-plug by screw-threading the parts or by crimping, swaging, or other suitable manner reducing the I end of the barrel in slze of the rear I order to swage the shot as it is forced through that portion of the true barrel. The rear of the barrel is thus firmly held in the magazine breechplug. The magazine breech-plug, with the barrel secured therein as heretofore pointed out, is inserted within the false barrel or magazine 4, so that the front end 5 of the barrel flushes with the screw-threaded magazine-cap 6. The magazine-cap 6 is provided with an overlapping flange 7 threads which engage the nmer screwthreaded surface of magazine 4, the bar rel passing into opening 8 in the screwthreaded cap, so that by removing screwthreaded cap 6 the shot may be turned into the magazine, and by replacing it the magazine is closed and the gun is ready to be loaded. For permanently locating the mag azine breech-plug 3 I insert tubular stop 9, slotted at 10 in the direction of its length and which is inserted in the outer or false barrel or magazine and suitably secured to the inner surface of the magazine or false barrel. I accomplish this, preferably, by tinning its outer surface, so that when it is in place and heat is applied to the parts they become soldered together. It then acts as a stop against which the magazine breech-plug is held Within the magazine or false barrel as an abutment in the operation of the piston.

Magazine breech-plug 3, carrying barrel 1, is inserted in the magazine at the rear of the slotted tubular stop, the front edge of the magazine breech-plug resting against the edge of the stationar T tubular stop and rear- Wardly of the same, where it may be suitably secured. For permitting the shot Within the magazine to be fed. into the true barrel I provide a passage-way through the breech-plug, which in this instance consists of horizontal o ening 12, intersecting cross-opening 14, so t rat a single shot may enter opening 12 and drop through opening 14 to the rear end of the true barrel in place for projection. The opening 13 is incidentally formed in the convenient cutting of space 14. The tubular magazine 4 is of the same diameter from end to end and is constructed ordinarily of metal tubing.

For operating upon each successive shot as and is provided with screw' it passes into space 14 and discharging the same I provide a movable tubular piston or plunger 15, which is sufliciently small to pass the false barrel and the magazine breech-plug with a peripheral groove for supporting the ment 28 is formed substantially as shown,

into the bore of the true barrel 1 when driven pin 32 passing through the stock, the other forward. At the rear end of the magazine breech-plug I bore or tap a hole 16 of suflii rod 20 when the gun has cient diameter to freely admit piston 15, which can be driven through opening 16 into 1 drawing rod 20 back, compressing spring 27, the bore of the barrel mounted in the magai and bringing tip 22 of rod 20 into engagezine breech-plug. The piston 15 is provided ment with catch 23 on the trigger.

with opening or slot 17 through its wall, Fig. i Changes and modifications in the construc- 1, which permits the compressed air from the 1 tion of my airgun maybe made by one skilled air-chamber 18 to pass through this opening in the art without departing from the spirit and through the tubular piston 15 and of, my invention. In the description I have against the shot at 14 and project it from the pointed out one of the ways in which I have true barrel 1, following the shot and exercispracticed my invention and the one which I consider best.

ing its elastic influence upon 1t until it leaves the bore of the barrel. What I claim as new, and desire to secure by Letters Patent, is

The air-chamber 18-is formed by the wall of l j 1. In an air-gun having a magazine between the walls of a false barrel and a true barrel and having a removable cap at the outer end and a removable plug at the inner end, the combination, of means for removably fixing the said same, said means consisting of a tubular member slotted through its length, adapted to be compressed to be slipped into place and coated with a material whereby, through the applicationof heat to the parts it may become soldered in place to hold the plug and plug, substantially as shown.

2. In an air-gun, a removable breech-plug, and a slotted spring-sleeve having its outer l surface prepared to be secured by the application of heat adjacent the plug to hold the same in place and removable to permit withdrawal of the plug, substantially as shown.

3. In an air-gun, a removable breech-plug, and a slotted spring-sleeve having its outer surface prepared to be secured by the application of heat adjacent the plug to hold the same in place, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

been discharged and at its front and at the rear by the piston-head 19, which is packed with oiled wicking or other suitable material for making the same airtight, the piston-head being provided wicking or other packing. Attached to the piston-head 19 I provide piston-rod 20, which extends rearwardly and terminates in hook or curve 21, the tip of which, 22, engages with catch 23 on trigger 24, pivoted in the frame at 25 and held in its position by coilspring 26, one end of which bears on the trigger, the other end resting in a pocket in the frame.

At 27 I show a coil-s ring suitably suported, one end of whic1 bears against piston-head 19, which is movable, the other end bearing against abutment 28. The spring is put under compression by drawing back the piston-head 19, as hereinafter shown. Abutfor the reciprocal play of rod 20 and having longitudinal slot 30 for like play of hook 21 of that rod and holding the same in its proper position with the curved end downward, so as to be engaged by the catch 23 on the trigger when the gun is being charged. For compressing coil-spring 27 I provide in this instance a wire pull or link 31, which is held by I Fig. 5, having a groove 29 in the squared end j Witnesses:
